void vApplicationPingReplyHook( ePingReplyStatus_t eStatus, uint16_t usIdentifier );
vApplicationPingReplyHook() is an application defined hook (or callback) function that is called by the IP stack when the stack receives a reply to an ICMP echo (ping) request that was generated using the FreeRTOS_SendPingRequest() function.
Callback functions are implemented by the application writer, but called by the IP stack. The prototype of the callback function must exactly match the prototype above (including the function name).
eStatus will be set (by the IP stack) to one of the
The identifier received in the echo reply.
Each echo request has a unique identifier to allow replies to be matched to the requests. The FreeRTOS_SendPingRequest() function returns the identifier of the outgoing echo request it generated.
The example on the FreeRTOS_SendPingRequest() documentation page includes an example implementation of vApplicationPingReplyHook().
